| Abstract: | A fiber digital broadcast system of hi-fi sound is developed in use of fiber as transmission medium.The fiber digital broadcast system consists of loudspeaker and fiber broadcast equipment,two core fiber,centre controller,management software.The WDM technique is used in the light transmission module of fiber broadcast equipment.And the net is formed as a "circularity",and develops to a self-heal ring.The light signals of two different kinks of wavelengths can be transmitted in a single core fiber,and that makes long distance transmission with high speed and stability possible. |
